Just saw some amusing slides from a company about their recent acquisition of a similarly-sized company and how it's a good move strategically. Some of the justifications, translated into my own words:

We're bigger now! (bar chart)

Acquired company does enterprise and we don't!

Acquired company is in other markets that we're not! (pie charts)

Acquired company makes products that are different from ours, so now we can be a greater percentage of the total solution!

Acquired company has revenues and profits, which when added to ours, makes the total bigger! (line charts)

Summary: all of the above would also be true if a software company acquired a breakfast cereal company.
